摘 要:以IEC 61850-5標(biāo)準(zhǔn)規(guī)定的D2-1配電變電站為實例,利用OPNET軟件建立了統(tǒng)一組網(wǎng)和獨立組網(wǎng)的變電站通信網(wǎng)絡(luò)仿真模型,并基于該模型對兩種組網(wǎng)方式的網(wǎng)絡(luò)性能和VLAN技術(shù)對變電站網(wǎng)絡(luò)性能的影響進(jìn)行了對比分析。仿真結(jié)果表明:兩種方案下各交換機(jī)負(fù)載獨立組網(wǎng)低于統(tǒng)一組網(wǎng);以太網(wǎng)延時統(tǒng)一組網(wǎng)高于獨立組網(wǎng);VLAN技術(shù)對統(tǒng)一組網(wǎng)網(wǎng)絡(luò)性能的影響較獨立組網(wǎng)大。

Abstract: Taking substation D2-1specified by IEC 61850-5 for example, this paper established the unified networking and independent networking dynamic simulation models of substation communication network using software OPNET. Based on the built models, this paper analyzed and compared the impacts from the network performance and virtual local area network (VLAN) technology of the two networking modes on substation network performance. The simulation result shows that each exchanger of load independent networking is lower than that of unified networking, the Ethernet delay of unified networking is higher than that of independent networking and the VLAN technology impacts on unified networking more than on independent networking.
Key words: smart substation; IEC 61850; OPNET simulation; unified networking; independent networking; virtual local area network
